ONX4050044ONX4050044
In the OFF position, pull the lever gently
toward you to spray washer fluid on the
windshield and to run the wipers 1-3
cycles. The spray and wiper operation
will continue until you release the lever. If
the washer does not work, you may need
to add washer fluid to the washer fluid
reservoir.
Recirculating air when washer fluid
is used
When washer fluid is used, in order to
reduce any unpleasant scent of the
washer fluid from entering the cabin,
recirculation mode and air conditioning
are automatically activated depending
on the outside temperature. If you
select fresh mode while the function is
operating, the function will resume after
a certain amount of time. It may not work
in some conditions such as cold weather
or engine OFF.
For more details, refer to “Climate
Control Additional Features” section in
this chapter.
WARNING
When the outside temperature is below
freezing, ALWAYS warm the windshield
using the defroster to help prevent
the washer fluid from freezing on the
windshield and obscuring your vision
which could result in an accident and
serious injury or death.
NOTICE
• To prevent possible damage to the
washer pump, do not operate the
washer when the fluid reservoir is
empty.
• To prevent possible damage to the
wipers or windshield, do not operate
the wipers when the windshield is
dry.
• To prevent damage to the wiper
arms and other components, do
not attempt to move the wipers
manually.
• To prevent possible damage to the
wipers and washer system, use anti-
freezing washer fluids in the winter
season or cold weather.

Air intake control
This is used to select the outside (fresh)
air position or recirculated air position.
To change the air intake control position,
push the control button.
Recirculated air position
With the recirculated air
position selected, air from the
passenger compartment will
be drawn through the heating
system and heated or cooled
according to the function
selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air enters
the vehicle from outside
and is heated or cooled
according to the function
selected.

Convenience Features5-106
Information
Using the system in the fresh air position is
recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging of
the windshield and side windows and the
air within the passenger compartment will
become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in excessively
dry air in the passenger compartment.
WARNING
• Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure
visibility.
• Do not sleep in a vehicle with the air
conditioning or heating system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.
• Continued climate control system
operation in the recirculated air
position can cause drowsiness
or sleepiness, and loss of vehicle
control. Set the air intake control
to the outside (fresh) air position as
much as possible while driving.

System Maintenance
Cabin air filter
OIK047401LOIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning system.
Therefore, if abnormal operation is found,
have the system inspected by an authorized
HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING
Windshield heating
Do not use the
position during
cooling operation in extremely humid
weather. The difference between the
temperature of the outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position
and fan speed control knob to a lower
speed.
• For maximum defrost performance, set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice from the windshield, rear window,
side view mirrors, and all side
windows.
• Clear all snow and ice from the hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.
